Ryukyu Kajika frog – Amphibians of the Ryukyu Islands

Posted on February 27, 2017 by Admin11

The Ryukyu Kajika frog ( Buergeria japonica ) is found throughout the Ryukyu Islands. It is the most common frog found on Okinawa.

Scientific name: Buergeria japonica
Common name: Ryukyu Kajika frog
Distribution: Ryukyu Islands
Habitat: Forests, mountain slopes, drainage ditches and farm fields.
Diet: Small Insects
Average size: 25mm-40mm

This small frog is a master of camouflage. I often find it on rocks, plants, trees, drainage ditches and even our trash.

This is the only frog on Okinawa that is capable of living on the shoreline next to the ocean. I have photographed them as close as five feet away from the saltwater.

The eggs are laid in slow-moving and still water sources. The eggs will develop into tadpoles and eventually transform into baby frogs. I often find tadpoles thriving in farming water buckets.

The summer months provide a great opportunity for natural predators.The frogs come together in large numbers.

If you see frogs, there is a possibility that snakes are nearby. The snakes patiently wait for frogs in drainage ditches and still water sources. The Kajika frog is the Hime habu’s favourite meal.

Meet Your Neighbours project – Okinawa, Japan

Posted on October 22, 2016 by Admin11

Founded in 2009, Meet Your Neighbours is a worldwide photographic initiative created by Niall Benvie and Clay Bolt. The project is dedicated to reconnecting people with the wildlife on their own doorsteps and enriching their lives in the process. These creatures and plants are vital to people: they represent the first, and for some, the only contact with wild nature we have. Yet too often they are overlooked, undervalued.

There are seventy-five worldwide contributors to this powerful project. I am currently the Japan contributor to this project. All images are used for conservation awareness and educational purposes. Below are some of my favourite images.

Okinawan Sword-tailed newt – Endangered species by Shawn Miller

Posted on October 5, 2016 by Admin11

The Okinawan Sword-tailed newt (Cynops ensicauda popei) is an endangered species found on the main islands of Okinawa an Amami. It is currently listed as endangered on the IUCN red list of threatened species. This amphibian is decreasing in numbers due to deforestation and road kill.

Scientific name: Cynops ensicauda popei
Distribution: Okinawa and Anami Islands
Habitat: Forests, wetlands and freshwater streams
Diet: Amphibian eggs, tadpoles, snails, worms and insects
Average size: 100-180mm

Sword tailed newt with stripes

They all have bright orange bellies, which serve as a warning sign to predators that they are poisonous. When threatened they produce a transparent skin toxin.

Poisonous animals are toxic if you eat them or ingest their secretions. Irritations may occur after handling these newts if you have open wounds. Avoid rubbing your eyes or placing your hands in your mouth.

The Sword- tailed newt is often found crossing the road on rainy days in northern Okinawa.

Newt crossing

The government has designed specialized wildlife steps for animals that get trapped in roadside drainage ditches. These steps allow the newts to crawl out safely.

The Art of Wide-Angle Macro Photography by Shawn Miller

Posted on December 20, 2014 by Admin11

Wide-angle macro photography is popular with wildlife photographers. The technique allows the photographer to document the animal in its natural habitat and show the full scene it lives in. The photographs have great impact and deliver a bug eye perspective using a wide angle lens. I generally use off-camera flash with a custom soft box to make these photographs. Lately, I have been testing a variety of on-camera flashes to achieve a different perspective. One of the biggest challenges is lighting the subject evenly with soft diffused lighting.

The most popular lenses used for wide angle macro photography ( WAM )

Tokina fisheye 10-17mm f3.5-4.5
Nikon fisheye 10.5mm f2.8
Sigma fisheye 15mm f2.8 E
Venus Laowa 15mm f4 – (Manual focus only)

The Tokina 10-17mm Fisheye is my favorite lens in my bag and has been my go-to lens for the project “Crabs with Beach Trash Homes”
